Answer:

The correct statement is option a, that is, when an electron drops down from a high energy level to a lower one, light energy is emitted.

Explanation:

The energy is quantized that is every orbit exhibits a fixed energy value. When the absorption of heat takes place by the atom, the electrons go from low energy level to the high level of energy. However, when energy or heat is discharged by the atom then the electrons travel from the level of high energy to the level of low energy. As a consequence, this heat is discharged in the form of visible light. Therefore, of the given statements, the accurate statement is that when an electron drops down from a high energy level to a lower energy level, the emission of light takes place.
